Application Scenarios & Design Considerations

Low Power Half-Duplex RS-485 Transceivers

Alternative Part Number

  • MAX481CPA --: Pin-compatible RS-485/RS-422 transceiver with the same 8-pin DIP footprint and equivalent electrical characteristics, widely available and a direct functional drop-in.
  • SN75176BP --: Industry-standard RS-485 differential bus transceiver in 8-pin DIP, functionally equivalent to the SP481 with similar driver/receiver specs and very broad availability.
  • ADM485ANZ --: Low-power RS-485 transceiver in 8-pin DIP with comparable data rate and pinout, suitable as a reliable alternative when the original Sipex part is unavailable.
  • LTC485CN8 --: Low-power RS-485 transceiver in an 8-pin DIP package with compatible pinout and similar drive/receive specifications, suitable as a drop-in replacement.
